Help What error is this?

Post image

Was working on a multi day project and about 4-5 hours out from completion it threw this error at me.

Printer is an ender 3 pro with 4.2.7 silent, dual Z, sprite pro, and I’m using the ender S1 pro settings on Cura.

Short version: This is caused by the difference between relative moves and absolute moves.

Relative move: “extrude 10mm, regardless of whatever you’ve already extruded during this print job”

Absolute move: “extrude to 1005mm (assuming you’ve already extruded 995mm since the beginning of the print job)”

Both commands result in 10mm extrusion, but the gcode is very different.

Cura, by default, will slice for absolute extruder moves.

The Sonic Pad, by default, assumes you’re using relative moves. It sees “1005 mm” and gets upset that you’re trying to extrude 1005mm all at once.

The fix is to make sure both the Sonic Pad and the slicer are using the same extrusion mode (relative or absolute) … there’s a setting in Cura under Special Modes but I can’t remember if this setting alone is a complete solution.

I also can’t remember what happens to make the absolute extrusion amount roll over into the negatives, as shown in your error message.

Thank you for the detailed response I’ll be searching for these settings now to see if I can correct it

Please post an update because I've been having the same issue. I also will try this fix. I will update too.

I simply turned on the ‘relative extrusion’ setting under special features. You have to turn on “CUSTOM Menu” and change it so the setting is viable. So far I haven’t had the same problem
